Last year we bought one of those RV covers from Camping World. It has a soft fabric that apparently allows air flow. Cost us $390 for the 35 foot version and it covers our 4108. If you put it on the right way around, there's a zipper door access. On the plus side, we live in British Columbia where it rains and rains all winter. We always have 6 desiccant containers inside the bus to deal with moisture. We still had interior moisture with the cover but it was cut down by 75% easily. Also the manufacturer claims that they have different fabric covers for the type of weather that you get in all parts of the country.

On the negative side, it was difficult to put on with all the roof apparatus we have and the material is flimsy and tears easily. Also finding a place to store it when not in use was a pain.

Thanks for the responses, the plan eventually is to have a hard cover, but for now , I am looking to make this old bus a little less obtrusive. I did finally just buy the bullet and buy the Adco Tyvek cover from camping world. Let's hope it makes things a little more appeasing to the eye for now.

We have a Adco cover that came with our 4905 . Just put it on this past Saturday. No real wind to speak of here ,so not worried about Paint wear. They have lots of ties underneath and front and rear so it stays nice and snug.we also have the wet snowy/ rainy BC winter climate to deal with .I would prefer a bus barn , but until that happens this will do.Mark
